4-[(3-Chlorophenyl)sulfanyl]-2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-5-methoxypyrimidine CAS 339276-07-2

Description

CATO supplies 4-[(3-Chlorophenyl)sulfanyl]-2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-5-methoxypyrimidine (CAS 339276-07-2), a certified reference material (molecular formula C18H13Cl3N2OS2, MW 443.80 g/mol) for analytical method development and quality control.

The molecular framework of 4-[(3-Chlorophenyl)sulfanyl]-2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-5-methoxypyrimidine (C18H13Cl3N2OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
